p This invention relates to an attachment for nailing machines and has for its primary object to provide, in a manner as hereinafter set forth, an attachment of suchclass by means of which a nailing machine may be utilized to nail and clinch the walls of a chicken coop with the rods or slats of the coop in position. a

A further object of the invention is to provide an attachment of the character aforesaid which includes adjustable means for supporting the parts being nailed, and which further includes adjustable means for clinching the nails, thereby adaptingthe machine for use in nailing and clinching the walls of a chicken coophavi'ng their rods or slats spaced varying distances apart.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more particularly described, and as illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that the description and drawings are tobe taken as illustrative and that the invention is intended to be limited only by the scope of the claims hereunto appended.

Referring to the drawings in detail, the

numeral 1 indicates a pair of side frame members of the nailing machine, said frame members being of angle iron construction. Thenailing machine as shown includes a nail receiving receptacle 2, from which nails are fed by a feeding means 3 and conducted through guide means 4 to the nail driving chuck 5, by means of which the nails are driven into the work indicated at 6. The nail driving chucks 5 are slidably mounted transversely 0f the machine in order that the same may be positioned to drive the nails at any distance apart desired. The foregoing elements are of well known construction and form no part of the present invention. The machine as shown also includes a work suporting table 7 which is vertically adjustable means of a crank 8.

My attachment includes a rigid support 9 which is preferably of I-beam construction and which extends transversely of the machine and is secured to a pair of rigid sup porting members 10 by suitable holdfast devices 10. The upper and lower flanges of the support 9 are notched indicated at 11 to slidably receive the frame members 1. The bars 10 extend vertically through slots 12 in the lower flange 13 of the support 9, and are rigidly secured at their lower ends to the table 7. The upper flange 11 of the support 9 is formed with beveled edges 12 in order that a plurality of work supporting members 13 may be mounted on the flange 11 to permit movement of the members 13 longitudinally of the support 9, and to prevent movement of the supporting members 13 transversely of the support 9. Each of the supporting members 13 is of elongated construction disposed transversely of the flange 11, and is formed in its lower face with a recess 14 Within which the flange 11 is received. The supporting members 13 may be properly adjusted lengthwiseof the support 9 to provide for the projection of the forward ends of the supports 13 between the slats 15 of the coop being nailed, and may be prevented from being moved from their set'positions 'by'means of set screws 16 which are threaded vertically through the supporting members 13 and bear against the upper face of the flange 11. The forward ends of the supporting members 13 are materially reduced in Width as indicated at 17 in order that the same may be extended between slats, such as 15 which are positioned relatively close together.

Secured to the rearward'face of the support 9, by means of suitable holdfast devices 18, area pair of curved bearing brackets 19 which support a rocker shaft 20 extending transversely of the machine. Fixedly secured to the rocker shaft.20 area pair of rocker arms '21'WlllCl1 extend forwardly through a support 9 and "rt All pair of slots 22 formed in the opening through the lower face thereof. rocker arms 21 have their forward ends pivotally connected with a rod 23which extends through openings 24 in the arms 21,

and which further extends through openings 25 in a pair of blocks 26 ad ustably supporting a plate 27. The plate 27 is of elongated formation extending transversely of the ma,

chine and includes a vertically disposed portion 28 and a rearwardly projecting, horizontally disposed portion 29. Threaded into the portion 28 and projecting rearwardly therefrom are a plurality of binding screws 30. The binding screws 30 are arranged in pairs with the screws of each pair arranged in vertical alignment. Each pair of the screws 30 loosely extend through apair of elongated slots 31 formed in a block 26 adjacent the ends of the block and disposed ver- 7 tically. thereof. Loosely rotatable through the horizontal portion 29 of the plate 27 are a pair of adjusting screws 32 which are threaded into openings 33 in the lower faces of the blocks 26. By manipulation of the adjusting screws 32,the plate 27 maybe raised or lowered with respect to the blocks 26,- and be rigidly secured to the blocks '26 then ma by tightening the bindthe vertical portion 28 ing screws 30. The rearward corners of the portion 29 are recessed as indicated at 29 to receivethe portions of the frame members 1 which project inwardly of the side edges of the plate 27 The portion 29 is formed in its'rear edge with recesses 28 for the passage therethrough of the bars 10.

Rigidly secured to the forward face of the portion 28 is a supporting bar 34 which extends transversely of the machine and is formed with'beveled upper and lower edges as indicated at 35. Slidably mounted on the bar 34 are a plurality of vertically disposed clincher bars 36 for abutment with the nails 37 to clinch the latter upon an upward movement of the plate 2?. Each of the clincher bars 36 is formed inits rearward face with a recess 37 having a beveled upper'edge 38 '39 of a recess 37,;tl1e head 40 further having a beveledupper face 411 forabutment with the beveled lower face 35 of the-bar 34;. By

loosening'the nuts 42 of the-securing bolts 39, the clincher bars 36 may be moved longitudi nally of the bar 34, and whenthe clincher bars are properly arranged with respect to the nails 3?, the bars may be secured against displacement by tightening the nuts 42which draws the headseO of the bolts 39 into engagement with the beveled lower face 35 of the I The means for moving the clincher bars into engagement with the nails includes a lever (l3,the upper endof which is fixedly mounted on the rocker shaft20. Thelever e3 extends downwardly through recesses 13" and e lim the flange 13 and portion 29'of the plate 27 respectively. The lever 43 is operated by means of a cam at mounted on a suitable shaft 45 carried by brackets 46 extending rearwardly from the frame member 1. Uponrotation of the cam 44, a peripherally projecting portion 4:7 thereof'is brought into engagement with the rearward end of a push rod48 which is slidably mounted in the bearing a9 of-a bracket 50 projecting rearwardly from one' of theframemembers 1. Upon a longitudinal movement of the push rod-4:8, the forward-end of thelatter is brought into engagement with the rear face of the lever whereby the shaft 20 is rotated which swings therocker arms 21 in an arc tolift'the plate 2?, bar 34, and clincher bars 36. V

In the use of the attachment, the height of the supporting members 13 is adjusted by means of thetable adjusting means in accordance with the thickness of'the parts to be nailed, and the supporting members 13 are adjusted longitudinally of the flange 11 in accordance with the distance between the slats of the coop being nailed, after which the parts of the coop to be nailed are seated on the forward end portions 1'? ofthe supporting members 13 with the latter arranged between the depending slats of the coop. Likewise the clincherbars 36 are adjusted longitudinally of the supporting-bar 34 in order to position the clincher bars in vertical alignment with thenail' driving chucks 5 of the the invention as defined in the appended claims WVhat I claim is: I 1.
